Is Your Camaro's Trunk Lock Failing?
For a classic car like the 1967-1978 Camaro, the trunk lock has seen a lot of use. After 50-plus years, it's common for these simple mechanical parts to wear out. Symptoms are usually obvious and can make accessing or securing your trunk a hassle.
Common signs of a failing trunk lock include:
- The key becomes difficult to insert or turn in the lock cylinder.
- The lock feels loose or wiggles in the trunk lid.
- You have to jiggle the key or lock to get the trunk to open.
- The trunk lid won't latch securely when closed.
- The key gets stuck or breaks off in the lock.
Rust is the Enemy
On these older vehicles, rust can be a major problem. Water can get into the trunk lock mechanism, causing it to seize. The support structure around the lock can also rust, making the entire assembly loose. If you see significant rust, you may need to replace the support bracket in addition to the lock itself.

Finding a brand-new, original GM part for a vehicle this old is nearly impossible. The market is served by aftermarket manufacturers who create reproduction parts. For a simple mechanical part like a trunk lock, a quality aftermarket replacement is a reliable and cost-effective choice. Here’s a breakdown of the available brand tiers.
Brand Quality Tiers
- Premium Aftermarket (ACDelco): ACDelco is GM's official parts brand and is often considered a top-tier choice for replacement parts. While not the original part made in the 60s or 70s, their products are designed to meet or exceed original specifications and are trusted by professionals.
- Standard Aftermarket (Standard Ignition): Standard Motor Products (SMP) is a long-standing, reputable brand in the aftermarket world. They are known for producing quality components that offer a good balance of price and reliability. Many technicians trust Standard parts for everyday repairs.
- Value-Oriented (Replacement): "Replacement" branded parts are typically the most budget-friendly option. For a simple, non-electronic part like a trunk lock cylinder, these can be a perfectly acceptable solution to get the job done without spending much.
Consider a Full Lock Set
If your door and ignition keys are also worn, this is a great time to buy a complete lock set. These kits include new cylinders for the ignition, doors, glove box, and trunk, all matched to a single new set of keys. This eliminates the need to carry multiple worn keys.
How Much Does a New Trunk Lock Cost?
Replacing the trunk lock on a classic Camaro is an affordable repair. The parts are not expensive, and if you have it done professionally, the labor is minimal.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Trunk Lock Cylinder | $14.75 - $31.10 |

Frequently Asked Questions
Is replacing the trunk lock a difficult job?
No, this is a very straightforward job for a DIYer.

🎬 See a step-by-step walkthrough for installing a new classic car lock.Are there any recalls for the 1967-1978 Camaro trunk lock?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls specifically for the trunk lock mechanism on these vehicles. Any recalls for vehicles of this age are long expired.
What if my trunk is stuck closed and the key won't work?
If the lock is completely failed, you may need to access the trunk from inside the car by removing the rear seat back. From there, you can typically reach the latch mechanism to release it manually with a screwdriver or pliers.
Can I just lubricate my old lock instead of replacing it?
You can try using a graphite-based lock lubricant as a first step. If the lock is just stiff from lack of use, this might free it up. However, if the internal tumblers are worn or damaged, or if rust is the problem, lubrication will only be a temporary fix at best. Given the low cost of a new lock, replacement is often the better long-term solution.
